Police were investigating an abandoned package at Red Rock Resort Tuesday night after it caused several casino employees to become sick, police said.
Las Vegas police received a call at 7:10 p.m. Tuesday about a suspicious package inside the east parking garage at the Summerlin casino, said police spokesman Officer Jose Montoya.
The package was taken to the security office, where personnel determined it was a pillowcase containing credit cards and a driver's license, Montoya said.
Casino employees then noted an odd odor coming from the package, and about five employees complained of feeling ill, police said. Montoya said the employees became nauseated and started sweating profusely.
The employees were treated on site after it was determined that their symptoms were not life-threatening, Montoya said.
There were no evacuations of the casino, but Las Vegas police at about 10:30 p.m. dispatched its team that inspects suspicious packages to the casino security office.
"Our armor team is here, they're suited up and they are trying to determine what the unusual odor is coming from this package," Montoya said.
